Genesis of autotractor diesel engineering and first diesel tractors

Abstract

Agriculture needed a simple engine running on cheap fuel to switch to mechanical traction. Due to its simplicity and ability to work on oil, colorization engines have become widespread, including in agriculture. (Research purpose) The research purpose is in identifying the key issues that influenced the creation of diesel engines with divided combustion chamber: indirect, pre-chamber, as well as studying the story of the creation of the indirect diesel, the first diesel tractors. (Materials and methods) The article notes the importance of the International Congress of figures involved in the construction and use of internal combustion engines, and the exhibition organized at the same time. The exhibition presents 95 engines, 23 of them were created at Russian factories. The holding of the international event and the wide participation of domestic engine manufacturers in it testified to the development of engine design in Russia. (Results and discussion) The article notes that despite the success of the world engine building, the problem of creating a lightweight diesel of high specific power, suitable for installation on automotive equipment, has not been solved yet. The article consideres the history of creation of a high-speed turbocharged diesel engine with a "soft" flow of the working stroke. (Conclusions) A two-cylinder pre-chamber diesel engine with a capacity of 18 kilowatts (25 horsepower) at 800 rpm by P. L'Orange was produced by Benz & Cie in 1922 and intended for agricultural machinery. The Benz-Sendling S6 motor plow with the Benz & Cie diesel was launched in March 1923. In addition to three-wheeled tractors and motor plows, since 1923, Benz and Sendling have offered a four-wheeled model of the BK diesel tractor. The first serial diesel tractor in Europe is considered to be the Deutz tractor. Produced in 1927, the MTH 222 tractor was equipped with a 14-horsepower single-cylinder engine with an additional chamber.
